Spoilers ahead
The film is told through Rawson’s point of view of the killings of Dennis Rader. Rawson is interviewed about what life with her father was like when she was a child. The documentary shows multiple family media from when Rawson was a child, explaining how she had a normal childhood.
In 2005, two FBI agents arrive at Rawson’s door. They inform her that her father has been arrested as the BTK killer. The documentary then shows the two versions of her father. To his family and neighborhood, Rader was a devoted husband and father. He used this to hide his crimes, which began before Rawson was born in 1974. Rawson shares memories of her childhood and her good connections with her father. However, she also shares memories on night terrors, bed-wetting, and a constant fear of home invasion. She now believes that it was her subconscious mind reacting to “a bad man in the house”.
The arrest and media put Rawson’s family into disbelief and trauma. She upends her life and forces herself to question everything she ever believed. She deals with immense grief, public scrutiny, and lasting emotional trauma, including PTSD. Over the years, Rawson struggles with a moral dilemma as she helps investigators search for more victims of her father. Rawson eventually visits her father in prison. She confronts him about his crimes and asks about other victims, but he evades her questions. She also confronts him about a disturbing fantasy he wrote in his notes that included her name, which he says that it’s just a fantasy.
After spending nearly a decade in silence, Rawson is inspired by a Stephen King interview to tell her story. She tells her narrative, and becomes an advocate for victims. The documentary finishes with Rawson reflecting on her last prison visit with her father. She realizes that her own healing and identity will not be defined by his actions. The film concludes with her moving forward and closing that chapter of her life.

The final act, in full
The film closes on the uneasy aftermath of Dennis Rader’s arrest, showing Kerri Rawson’s final, painful encounter with the man who raised her. After the FBI used her university DNA sample to confirm her father’s identity, she began visiting him in prison – a move meant to coax any hidden confessions. During one such meeting she confronted him about a note he’d kept that listed her name in connection with his twisted “bondage games,” suggesting she may have been assaulted as a child. Rader flat‑out denied any wrongdoing against his family, and Kerri, feeling the weight of his lies, cut off all further contact. That conversation becomes the documentary’s emotional climax, underscoring how the horror of his crimes extended beyond the victims he killed.
The ending then shifts to the present, revealing the divergent paths the two have taken. Rader, now in his eighties, remains incarcerated at the El Dorado Correctional Facility, serving a 175‑year sentence for ten murders and the countless taunts he sent to the media. Kerri, meanwhile, lives a quiet life in Kansas with her husband and two children, keeping her address secret while continuing to speak out about the trauma of being “the daughter of a serial killer.” Her childhood home has been razed, leaving only an empty lot, a stark symbol of the effort to erase the physical reminder of the nightmare. The documentary ends on a lingering note of unresolved pain, hinting that Kerri may never fully know whether she herself was directly victimized, but she has chosen to keep telling her story on her own terms.
